在具有 z-index 和叠加层的背景图像不影响导航栏的情况下创建边距

Question

我正在尝试创建一个网页，其中我有固定的 50px 边距，其中页面图像有一个索引，使其更靠近屏幕并且边距看起来更远 off.I 也想要为了实现固定的页脚，就像我在导航中所做的那样 bar.I 尝试将左右边距设置为 50px 并将它们设置为固定位置并尝试使用包装器 class 添加到两个部分都没有产生期望的结果。

下面是我的代码

Answer 1

您没有使用 id 选择器来引用 css 页面中的页脚部分，可能您在 CSS 文件的底部引用了 #fixed 而不是页脚。

// 用这个代替

 #footer{
 position: fixed;
 bottom: 0;
 left: 0;
 height :50px;
 width:100%;
 background-color: transparent;

}

您在菜单导航、部分和子 divs (#portfiolio) 上使用了相同的选择器，您需要学习如何正确创建布局并正确使用 css 选择器。你可以免费学习 udemy 网页设计入门。他们的解释非常好，还有 Kenvin Powell 在 Youtube 上介绍 css 课程。

快速修复得到一个 parent div 和 2 children

<div class="parentDiv">
   <div class="bgDiv"></div>
   <div class="contentDiv></div>
</div>

假设当前屏幕尺寸为 746 像素，您可以使用这些单位来获得所需的输出

.parentDiv{
   width: 646px;
   max-width: 100%;
      position: relative;
   max-width: 100%;
   margin: auto;
   perspective: 500px;
   height: 100%;

 }
.bgDiv{
      box-shadow: inset -3px -70px 8px 6vw rgba(255, 255, 255, 0.8);
   background-image: linear-gradient(rgba(245, 242, 242, 0.44), rgba(255, 
    255, 255, 0.5)), url(https://placebear.com/500/300);
    position: absolute;
    top: 0;
    left: 0;
    width: 100%;
    height: 100%;
    background-repeat: no-repeat;
    z-index: -999;
    background-size: cover;

}
 .contentDiv{
  position: absolute;
  z-index: 999;
  top: 20px;
  left: 50px;
  transform: translate3d(25px, 25px, 50px);
  padding: 4rem;
